IMPROVEMENT IN LOOM PICKER-SPRINGS.

Specification forming part of Letters Patent No. 151,545, dated June 2, 1874; application tiled February 7, 1874.

To all whom. Ait may concern:

Be it known that LWILLIAM E. N. POTTER, of Lewiston, in the county of Audroscoggin and State of Maine, have invented a new and Improved Loom Picker-Swing, of which the following is a specication:

The in vent-ion relates to mounting a springpulleyT (around which is wound the strap that connects it with the picker-stick) on a crotched stand having a slotted base to adapt it to be secured to a screw-stud in a vertical or horizontal position. lt also relates to the means of securing the strap to the pulley-ease, as hereinafter described.

Figure l is a sectional elevation ol" a springpnlley mounted on a stand constructed accoi-ding to my invention. Fig. 2 is a horizontal section taken on the line a' a' of Fig. 1. Fig. 3 is a horizontal section taken on the line y y of Fig. l. Fig. 4 is partly aside elevation and partly a section when the stand is attached to the side of a vertical support. Fig. 5 is a detail view, showing the arrangement of the band-hook.

Similar letters of reference indicate corre sponding parts.

A represents a hollow double-anged pulley, containing a dat coiled spring, B, mounted on a spindle, C, having a erotched standard or support, D, projecting from a base-plate, E, which has a slotted hole, F, through it for the fastening stud-screw G of a floor-plate, H, or bolt I of a standard,vJ. The spring is connected at 011e end to the spindle, and at the other end to the rim of the pulley, and a hook, L, is employed to connect the strap .K to the pulley, the hook being fastened in the slot in the face of J(he pulley by its bent portion M and the straight etension N, said extension being pressed in between the two coils of the spring, and kept in place by them.

This arrangement allows ot readily putting in the hook and taking it out, so that a broken or worn-out hook can be readily replaced.

Having thus described 1n y invention, I claim as new and desire to secure by Letters Fatent- 1. The crotehed standard D and slotted stand-plate E, in combination with the spindle O, pulley A, and spring B, snbstai'itially as speeitied.

2. The strap-hook L, secured to the pulley by its bent part M and extension N, as described. l
